Hello!
Before the update you launched last monday (23rd), my fps in the game was somewhat stable at 60-70, which is acceptable when it comes to multiplayer gameplay.
After the patch I have been spiking all the way down to 20 fps, and up to 120 with certain fps configs, tips and tweaks.
I have tried 5 different fps configs, from basically all over the place. I have tried different drivers for my graphics card, and I am currently running on the 10.5 version of ATIs CCC, which seems to be working slightly better than 11.5b.
My rig is the following;
Dual intel E8500, 3.2ghz
ATI radeon hd serie 5770
4gb 667mhz ddr2 ram
sufficient mobo and harddrives.
The problem here is that brink is the only game that doesn’t allow me to play properly. At all. I have played several new games and gotten a great and stable fps on them.
After spending some time on google, I see that it seems to be a problem when it comes to ATI cards and Brink. I do not know if this is ATI’s fault or Brink’s fault, but I know that it is currently unplayable for me, and that has to change.
The problem here is clearly not the specs on my card, in my opinion. People can play with nvidia cards that have worse specs than my 5770 card, and still get above 100 stable fps more than me.
I will not buy an nvidia card for a single game when other games I play, like StarCraft2 work excellent on my current rig, and pull at least the same amount of force as Brink should be doing.
Summary:
Problem: poor fps on ati 5770
Solution: None(?)
Adaption: I am willing to help you in any way to fix this problem. I think Brink is a good game, when it can be played.
If you have any constructive ideas or suggestions, feel free to post them here. I do not mind helping you in testing of certain ideas whether they are related to Brink settings, updates or my rig.
